I am a new homeowner and I'm having an issue where water is dripping through my bathroom fan duct into my bathroom. The fan duct goes up into the attic.
The dripping worsens when a shower is taken.
I've had a plumber come out who's said there isn't a leak. I've also had a roofer come out to ensure the roof wasn't leaking, so no issues there either.
Does anyone have any ideas of possible causes (even which specialist could help with this) because as at the moment I am running out of ideas. I believe condensation could be a possibility but as the cost of new insulation would be high I want to rule out any other causes before going down that route.
Thanks in advance,
